Of course! With apgnano's generation algorithm, that's probably not too much more CPU time than the current 33-cell search. But will you just have apgnano run each pattern to stabilization and then census the results? That makes a 37-cell enumeration look a little more ambitious, but still probably within reach I would guess.

I would guess that unless we filter them out with an apgsearch/apgnano hack, there will probably be hundreds of these kinds of oscillator results before the first spaceship is likely to show up. Probably mostly p10 like this one, though there are other combinations that CopperSearch doesn't forbid, like p12 or 24 -- pulsar plus something p4 or p8.

So: 130 through 132 have been checked now -- no results.

Is this a new oscillator? Probably not...

That that is, is. That that is not, is not. Is that it? It is.A predecessor to my favorite oscillator of all time:
